Expert Solution
Step 1

Since you have posted a question with multiple sub-parts, we will solve the first three sub- parts for you. To get remaining sub-part solved please repost the complete question and mention the sub-parts to be solved.

Step 2

Consider the equation of the position of the particle.

Physics homework question answer, step 2, image 1

Since the x in the equation represent the distance along x-direction. Therefore, the unit of x will be “m” and the unit of time t is “s”. The terms on the right-hand sign of the equation are in subtraction. Thus, the unit of each term is independent of each other and it is equivalent to “m”.

Step 3

(a)

Consider the first term and equate it to the unit of x that is to “m”, simultaneously substitute the unit of time for time.

Thus, the unit of the constant c is m/s2.
